In a one billion dollar lawsuit, U.S. Navy sailors contend that they “suffered massive doses of radiation” from the Fukushima Dia-ichi nuclear power plant in Toyko, Japan while stationed on the USS Ronald Reagan, reported the Orange County Register. A tsunami (caused by a 9.0 earthquake) flooded the plant, “cutting off electrical power and disabling backup generators.” The USS Reagan was sent to provide aid, but the plant then “blew up” before they arrived.

“Sailors on the flight deck said they felt a warm gust of air, followed by a sudden snow storm: radioactive steam,” according to the Orange County Register. “Freezing in the cold Pacific air. Blanketing their ship.”

However, the Orange County Register posed the question, “Could the Reagan – one of the most advanced nuclear aircraft carriers in the U.S. fleet – really not know that it was being showered with massive doses of radiation?” TEPCO, the company being sued by the sailors, answered that it’s “wholly implausible.”
